SOLDERING-FURNACE.

Specification of Letters Patent.

Application filed July 1, 1911.

Patented Mar. 11, 1913.

Serial No. 636,390.

To all whom t may concern:

Be it known that I, FREDRIGK H. DENICKE, a citizen of the United States, residing at Mauston, in the county of Juneau and State of Wisconsin, have invented new and useful Improvements in Soldering-Furnaces, of which the following is a specification.

This invention relates to furnaces using a volatile liquid such as gasolene for fuel and designed chieliy for heating soldering irons or the like, said furnace being portable and intended chiefly for use by plumbers and tinsmiths.

The primary obj ect of the invention is the provision of tubes which may be utilized for storing air7 or as a supplemental reservoir for carrying fuel, particularly when the usual tank will not contain a sutlicient quantity for a job or piece of work and avoiding the necessity for carrying an eXtra supply of fuel in a can or other receptacle.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claim.

Referring to the drawings, forming a part of the specilication, Figure 1 is a side view of a soldering furnace embodying the invention. Fig. 2 is a top plan view of the furnace having a part broken away. Fig. 3 is a sectional elevation. Fig. 4 is a horizontal section on the line m-x of Fig. l.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawings, by the same reference characters.

The essential parts of the furnace are mounted upon a base l which is hollow. A tank 2 is mounted upon one end of the base and the furnace 3 is mounted upon the opposite end portion of the base and may be of any construction such as commonly employed for heating soldering irons. The tank 2 contains the gasolene or other volatile liquid fuel for supplying the burner of the furnace. A pipe 4 connects the tank 2 with the burner a and conveys the liquid fuel thereto. Pipes 5 and 8 connect the upper portion of the tank with a tube 6 and with .the pipe 4 to supply air thereto under pres'- siIre, thereby economizing in the consumption of the fuel and insuring the production of a clear flame. The tubes 6 and 7 are located within the hollovs7 base 1 and form storage chambers for holding air under pressure or for receiving an eXtra supply of gasolene or like volatile liquid. The two tubes 6 and 7 are connected near opposite ends by means of tubes Zi. The pipe 5 connecting the tube 6 with the upper portion or air space of the tank 2 has a valve 9 in its length. A second pipe or tube 10 connects an end portion of the tube 7 with the lower portion or fuel space of the tank 2. The pipe 10 has a valve 11 in its length. An air pump 12 secured to a side of the tank 2 is connected at its lower end with the tube 7.

`The tank 2 is adapted to be supplied with gasolene or other liquid fuel through a plug controlled opening c in its upper end. Upon operating the pump 12 the tubes 6 and 7 and the upper portion of the tank 2 may be charged with air under any desired pressure and after said parts have been charged the valve 9 is closed, thereby confining the air in the tubes 6 and 7 so as to be drawn upon as occasion may require to replenish the air space in the tank 2. Should it be required to carry an eXtra supply of gasolene or liquid fuel the tubes 6 and 7 are used as storage chambers for receiving the eXtra quantity of fuel. In this case it will be necessary to operate the pump 12 to supply any deficiency in air pressure in the tank 2. Upon opening the valve 11 and operating the pump l2 the gasolene may be forced from the tubes (i and 7 into the fuel or liq uid space of the tank 2. It will be understood that each of the pipes 4 and 5 is provided with a valve for regulating and controlling the opening therethrough so that the amount of fuel passing to the burner and the amount of air supplied to the flame may be adjusted to meet existing conditions so as to secure the best possible results. A

pipe 12 leads from the pipe 4 and terminates' lldesire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claim appended hereto.

Having thus described the invention what is claimed as new, is

In a device of the class described, a hollow base, a furnace mounted upon an end portion of the base, a tank located upon the opposite end portion of the base, v'alved connections between the upper and lower portions of the tank and the furnace, connected tubes arranged within the base, a valved pipe connecting one of the tubes with the upper portion of the tank7 another valved pipe connecting another tube with the lower portion of the tank, and a pump for charging the tubes with air under pressure.

In testimony whereof l aiix my signature in presence of two witnesses.
